Metamaterials (MTMs) are artificially engineered materials with unique electromagnetic
properties not occurring in natural materials. MTMs have gained considerable attention …

The detection of chemical samples having close dielectric response is a big challenge as
the detection principle is driven by the variations in the dielectric parameters of the …

Metamaterials (MTMs) are artificial structures characterized by flexible and designable
electromagnetic (EM) properties, including permittivity, permeability, and refractive index …

Since 2004, my group at Southeast University has been carrying out research into
microwave metamaterials, which are classified into three catagories: metamaterials based …

In this research paper, the sensing capabilities of a tri circle split ring resonator shaped
metamaterial is shown within the X-band frequency range for detection of various oil …

A method for designing circularly polarized (CP) horn antenna is proposed, which is based
on a standard pyramidal horn with a linear-to-circular polarization transformer. A compact …

In this article, we present an ultrawideband and high-gain antenna based on a 3-D
impedance-matching metamaterial (IMM) lens. First, we design a 3-D IMM lens which can …

Monolithic integration of 3-D printed gradient index (GRIN) dielectric loading with a double-
ridged rectangular horn standard gain horn (SGH) and its impact on antenna performance …

Low reflection, low-loss, and wideband graded-index (GRIN) flat artificial dielectric lenses
utilizing GRIN antireflection (AR) layers are developed in this paper. The GRIN lens and the …

The paper presents a method to design beam-steering antennas using a pair of 3D printed
perforated dielectric structures (PDSs) placed in the near-field region of a base antenna …
